Discover how the classic 555 timer IC can be transformed into a compact Class-D stereo audio amp using its built-in oscillator and modulation capabilities. This project offers an unexpected way to ...

A two digit counter is an electronic device that counts from 00 to 99 and displays the count on two 7-segment displays. With each clock pulse, the displayed value increments, resetting to 00 after ...

The 555 timer IC, originally introduced by the Signetics Corporation around 1971, is perhaps one of the most popular analog integrated circuits ever produced. In this new Elektor book, the focus is on ...

Take a Raspberry Pi Pico and connect a 555 timer to one of its GPIOs. Arrange for the 555 to poke the Pico about 10 times a second. Treat that "poke" as an interrupt. On the interrupt, light the ...

Abstract: It is rare that an integrated circuit stays on the market for 25 years. And it is surprising that, except for a CMOS derivative, the 555 timer has never been updated. It has been shrunk ...

The venerable 555-type timer makes an effective driver for power MOSFETs, but you have to understand the drive situation when selecting the correct variation of the basic timer. This idea shows how ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...

Abstract: The 555 timer IC is a well-known integrated circuit having been widely used as a pulse generator. We propose a circuit containing a single 555 IC, an LED, an inductor, two capacitors, and ...
